Graphs of logarithmic functions
Teaching steps
1. Guide students through discussion to recognize the nature of
graphs of exponential functions. Assist students in using the

same procedures of sketching graphs of exponential functions
to sketch graph of logarithmic functions.

2. Design an activity that will engage students in sketching graphs
of logarithmic functions.
3. Use Examples 4.30 to 4.34 in the Student’s Book to guide
students to sketch graphs of logarithmic functions. Engage
students to use GeoGebra or any other mathematical software
to verify the answers of the given examples. Advise them to
make presentations for more inputs.

4. Instruct students to attempt Exercise 4.9 in the Student’s Book.
Advise students to submit their work, check the correctness of
the answers, and provide them constructive feedback where
necessary.
